MicroTCA TM - PICMG

Not Intended for Design - Do not Claim Compliance
The connector design shall ensure that no contact exceeds its current rating due to current balancing caused by
variations in contact resistance.
The connector high speed signal characteristic requirements on the AdvancedMC Backplane Connector may have
future refinements which will be based on the analysis of the allowable connector loss budget for 12.5 Gbps single
lane signal transmission on the entire channel.
The AdvancedMC Backplane Connector will be designed to withstand 200 mating cycles without damage that
would impair normal operation.
Engaging and separating forces
Table 3 Engaging and separating forces
Mating sides Force
Maximum engaging force 100 N
Maximum separating force 65 N
Maximum bottoming force 200 N
Under the conditions stated above, the force needed to engage and disengage an AdvancedMC Module PCB in the
AdvancedMC Backplane Connector shall not exceed the values given in Table 3. Additionally the connector will
withstand to 200 N at 1 minute duration of Module insertion-bottoming force, without damage that would impair
normal operation.
AdvancedMC Auxiliary Connector
To add connectivity to AdvancedMC Modules, the AdvancedMC Module and the Backplane may use additional
Auxiliary Connectors in the location shown Figure 23 in combination with the AdvancedMC Backplane Connector .
Additional design considerations are required when the Auxiliary Connector is used with an AdvancedMC
Backplane Connector. The tolerance stack up on these Connectors create misalignment which may cause of
damaging the Connector, short-circuit, and contact-off problems.
